Nui nā kahawai ma ka ʻāina o ka Leningrad Region, kahi e hoʻopili ai i nā ʻano o nā waihona o nā kumuwaiwai kūlohelohe. Ua hōʻike ʻia e ka noiʻi e nā kānaka hulihonua ua hiki i nā pele pele i ka wā kahiko ke hana i kahi nui o nā minelala e hoʻomohala ʻia nei a i ʻole me ka manaʻolana o ka hoʻouku.
ʻO ka Leningrad Region kahi ʻāpana waiwai, aia nā waihona o ka limestone, bauxite, shale, phosphorite, one, pālolo, peat. ʻImi ka ʻimi hohonu ʻana i nā kumuwaiwai kūlohelohe e hōʻike i nā mālama hou aʻe o nā kumuwaiwai kūlohelohe:
- ʻenekini;
- pōhaku hoʻopau;
- bitumen;
- ʻume mākala.
ʻO ka pāpaʻu hanana o nā bauxites i hiki ke huki iā lākou i kahi ala ākea. Hōʻike ʻia ka mining ʻana o ka lua puka o nā mea maka i kā lākou kumukūʻai. ʻAʻole like me ka bauxite, koi ka ʻaila a me nā phosphorites i ka mining.
Nā ʻano o nā minelala i ka ʻāina
I ka moku ʻo Leningrad nui nā mālama ʻia o ka granite, refractory a me ka pālolo pālolo, ka limestone, ke one mōlina. ʻO kēia mau kumuwaiwai e koi nui ʻia ma waena o nā ʻoihana kūkulu. Hoʻohui ʻia ʻo Granite ma ka Karelian Isthmus; ua loaʻa iā ia kahi noi i ka hoʻopau ʻana i nā hana i ke kūkulu ʻana. Ke hoʻomohala ʻia nei ʻo Limestone ʻaʻole mamao loa mai ke kaona ʻo Pikalevo.
Hāʻawi nā mākū i kahi manawa kūpono no ka huki ʻenehana o ka peat, kahi e hoʻohana ʻia i ka mahiʻai a me nā ʻoihana ʻenehana. Aia nā waihona peat nui loa ma ka hema a me ka hikina o ka ʻāina. ʻO ke kū ʻana o nā ululāʻau e hoʻolilo ka Leningrad Region i mea hoʻolako nui i nā lāʻau. Ma ka ʻĀkau Komohana o Lūkia, noho ka ʻāina i kekahi o nā wahi koʻikoʻi i ke kālai lāʻau ʻana.
Aia he 80 mau māla i ka mahele e hana nei i ka hoʻomohala hana. He 173 waihona a ka mokuʻāina ma kāna pale kaulike, nona wale nō 46% e hoʻomohala ʻia nei.
Loaʻa nā punawai minerala nui:
- ke kumu kūʻai ʻo sodium chloride Sestroretsk;
- wai sulfuric ma Sablino;
- ʻO Polyustrovskie carbonate ma St. Petersburg;
- ʻO nā punawai wai mineral kokoke i Luga (waihona wai wai wai ma lalo o ka honua).
No ka hana aniani, he mea nui ka unuhi ʻana i ke one, i hoʻohana ʻia e hoʻoheheʻe a hana i nā huahana aniani. Ua hoʻohana ʻia kēia kahua mai 1860 a i 1930. ʻO ke aniani imperial kaulana i hana ʻia mai kēia one. Ka lawe ʻia ʻana o nā pulu polū ʻo Cambrian ma ka ʻākau o ka ʻāina. Pau ka waihona hoʻokahi, a ke hoʻomohala ʻia nei ka lua e ka lua lua ʻana.
Ke hoʻomohala nei i nā minelala, hoʻohana ʻia nā ʻano o nā ana ʻana: ka hana ʻenekinia-honua; 'enekinia, a me geodetic; 'enekinia, a me hydrometeorological; ʻenehana ʻenehana.
Nā waihona waiho kālā i kūkulu ʻole ʻia
Aia nā waihona kālā o ke gula ma ka ʻāina, akā liʻiliʻi lākou i ka helu a ʻaʻole i hoʻomohala ʻia. Hoʻopiʻi kēia i kahi kahawai nui o ka poʻe ʻimi holoholona. Eia hou, aia nā waihona daimana, akā aia wale nō kā lākou ulu ʻana i ka papahana.
He nui nā waihona mineral i loaʻa ʻole i ka ʻāina, ʻo ia hoʻi:
- nā pena mineral;
- manganese;
- ʻume mākenēki;
- ʻaila.
Ua hana ʻia kā lākou ulu ʻana no ka wā e hiki mai ana, a e hāʻawi kēia i kahi manawa kūpono e hoʻonui i ka nui o nā hana a hoʻonui i ka moʻohelu āpana.
